Use A Strong And Unique Database Prefix

Why is the Default WordPress Database Prefix a Security Risk?

By default, WordPress assigns the database prefix as wp_, making it predictable and easy for hackers to target. Using the default prefix increases the risk of SQL injection attacks.

How to Change Your WordPress Database Prefix?

During Installation

Manually Changing the Prefix for an Existing Site

  1. Open the wp-config.php file and locate:
    $table_prefix = 'wp_';
  2. Change it to something unique, such as:
    $table_prefix = 'wpsecure_';
  3. Update your database tables using a plugin like WP-DBManager or iThemes Security to prevent errors.

2. Limit Database User Privileges to Secure WordPress Database

This file stores database credentials and WordPress configuration settings. If exposed, hackers can gain full control over your site.

How to Protect wp-config.php?

Placing it outside the public directory prevents direct access.

2. Restrict File Permissions

Set permissions to 600 using the following command:

chmod 600 wp-config.php

3. Block Access via .htaccess

Add this code to .htaccess:

<Files wp-config.php>
order allow,deny
deny from all
</Files>

9. Use SSL Encryption for Secure Database Communication

How Does SSL Protect Your Database?

SSL encrypts communication between your WordPress site and database, preventing hackers from intercepting sensitive data.
